Mechanical parameters

Main configuration of SS equipment

1. Vacuum material feeder (2 sets): a device used to suction and convey raw materials.

2. Screw extruders (2 sets): Equipped with electrically heated cast-aluminum heating bands to ensure proper melting of the raw materials.

3. Return-material screw (2 sets): an automatic feeding device. 
4. Filter (2 sets): A device used to hold filter elements, designed to remove impurities from the PP melt.

5. Metering pumps (2 sets): Devices used to meter the amount of PP melt. 
6. Spinning Box (2 sets): One of the key components of a melt‑spinning machine, the spinning box receives the polymer melt after it has passed through a filter. The melt is then distributed and thermally maintained within the box before being delivered to each spinning station for fiber formation. The box is a rectangular metal enclosure with an external insulation layer, housing the melt distribution manifold, pump mounting, and spinneret assembly. It also includes a fixture for securing the spinneret plate. 
7. Single‑unit suction system (2 sets): Ensures stable suction airflow and prevents any adverse effects on the tow. 
8. Aluminum cooling air boxes (2 sets): Low-temperature air is blown onto the aluminum surface at a high velocity to achieve cooling. 
9. Drawing units (2 sets): tempered glass; stainless steel construction. These units stretch the filament bundle, reducing its diameter and ensuring greater uniformity before it enters the web-forming machine. 
10. Insulation materials for oil pipelines: They feature a low thermal conductivity and excellent insulation performance, while also offering advantages such as flame retardancy, superior thermal stability, light weight, heat resistance, and strong resistance to chemical corrosion.

11. Web-forming machine (1 unit): Speed: ≤ 350 m/min 
12. Hot rolling mill (1 unit): Heating method: oil heating/thermal oil

13. Automatic winding machine (1 unit): Speed: ≤ 350 m/min 
14. Mesh curtains (2 sets): Serve to support the filament bundle as it moves toward the nip roller for bonding.

15. PLC Control Cabinet: The control cabinet serves to distribute electrical power and manage the power supply to the equipment. 
16. Slitting machine (1 unit): Slices large rolls of fabric into specified dimensions according to customer requirements, meeting the customer’s needs for product length, width, and roll weight. 
 

Application scenarios

 

 

 

 

SS Double-Beam Spunbond Production Line 
By connecting two spinning boxes in series, a two-layer spunbond web lamination structure is formed, resulting in significantly improved web uniformity and tensile strength compared to single-S products. 
Segmented application scenarios: 
Non-contact layer of hygiene products: Liner for composite use in diaper and sanitary napkin back sheets, and side-leakage‑preventing edge reinforcement layer 
Enhanced packaging materials: Heavy-duty shopping bags, industrial component bulk bags 
High-strength agricultural materials: Durable harvest mats for perennial crops and double-layer thermal insulation curtains for greenhouses.

Medical Protection Foundation Layer: Inner layer of medical masks (used in combination with the meltblown layer)
